Benefits of technology

[0011]The combination of co-generation with GHP as described in this disclosure can result in approximately 55% to 65% overall fuel savings and reduction in combustion emissions. To make this goal achievable it is also necessary to make co-generation practical by minimizing the engine of the co-generator use time by incorporating at least two appropriate heat storage tanks. The beneficial contributions of GHP also contribute to reducing the time required for co-generator use.

Problems solved by technology

No use of GHP and relies on interfacing with the electrical grid which can add associated costs.

Embodiment Construction

describes how this is accomplished for operation in the heating season mode and then for the cooling AC (air conditioning) mode.

[0014]Distribution modes to effectively use the energy from the two storage tanks are described. To support the understanding of this invention, examples and description of the involved heat pump are given.

DESCRIPTION OF DRAWINGS

[0015]FIG. 1 show three modes of energy consumption for air conditioning.

[0016]FIG. 2 shows three modes of energy consumption for space heating.

[0017]FIG. 3 is an engineering schematic drawing describing the elements of this invention in the air conditioning mode. FIG. 3A is flow schematic showing a set of conditions within the heat pump shown in FIG. 3. FIG. 3B shows a modification of FIG. 3 where refrigerant circulation from the heat pump flows thru a storage tank eliminating the need for certain components.

Abstract

A system and method are described for providing space heating and cooling along with tap water heating by combining the use of co-generation and a geothermal connected heat pump. The use of energy storage allows the intermittent use and extended life of the co-generator engine. These combinations provide marked energy savings and emissions reduction as compared to direct combustion and grid connected geothermal heat pump systems,

Description

[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 10 / 943,468 and includes portions of that application.BACKGROUND OF THE INVENTION[0002]Solar energy, geothermal / heat pump and co-generation of electricity have all been used to beneficial effect but each approach has major limitations for general US use. Solar either in the form of heat or electricity is costly and is severely limited for use in northern latitudes, e.g. New England.[0003]Geothermal for heating / cooling which is normally combined with heat pumps is also limited by latitude, but does not show major cost savings. This is because the system depends on electricity from the power grid to drive or supplement the heat pump. If the system has a COP(coefficient of performance) of e.g. 3 or a 67% btu savings, which is attractive, but it fails to meet actual cost savings because the electrical power / grid system approaches 30% net btu efficiency. In addition the electrical grid is stretched to the...
